Assessment of Critical Raw Materials by Addressing Sustainable Development Goals Using Fuzzy MCDM Approach

Abstract

Critical raw materials (CRMs), constituting the first step of the industry, are vital to meet sustainable development. With increasing digital technology and green transition efforts under the scope of twin transformation, demand for CRMs has increased, and supply interruption is expected in the future. All countries should plan the supply chain of CRMs in the context of the green and digital transition. The sustainable development goals (SDGs) have presented a reference based on sustainability metrics. In the chapter, hesitant-fuzzy analytical hierarchy process-based order preference technique based on similarity to ideal solutions (HF-AHP based TOPSIS) has been developed to evaluate the critical raw materials in the context of sustainability. Most relevant goals with the CRMs are obtained as SDG 1, SDG 3, SDG 5, SDG 6, SDG 7, SDG 8, SDG 9, SDG 11, SDG 17. The findings show how raw materials have important strengths and weaknesses in sustainable development. Policies recommended for the most important CRMs are effective road maps in the context of twin transformation.
